Abstract:
Generating a multimedia user interface with synchronized digital video and document content can include receiving a document, receiving a digital video that corresponds to the document, generating a plurality of mappings, wherein each of the mappings maps a section of the document to a segment of the digital video, and generating a multimedia user interface responsive to the document, the digital video, and the plurality of mappings.
Abstract:
Radio resource management for wireless cellular networks equipped with relay stations for multi-hop packet or protocol data unit (PDU) relaying.
Abstract:
Techniques, apparatus and systems for detecting particles such as muons. In one implementation, a monitoring system has a cosmic ray-produced charged particle tracker with a plurality of drift cells. The drift cells, which can be for example aluminum drift tubes, can be arranged at least above and below a volume to be scanned to thereby track incoming and outgoing charged particles, such as cosmic ray-produced muons, whilst also detecting gamma rays. The system can selectively detect devices or materials, such as iron, lead, gold and/or tungsten, occupying the volume from multiple scattering of the charged particles passing through the volume and can also detect any radioactive sources occupying the volume from gamma rays emitted therefrom. If necessary, the drift tubes can be sealed to eliminate the need for a gas handling system. The system can be employed to inspect occupied vehicles at border crossings for nuclear threat objects.
Abstract:
Apparatus, systems and techniques for implementing a servo controlled magnetic levitation system that magnetically levitates and controls a magnetic platform to navigate in a confined space to obtain capture images of or other information of the confined space. Medical surgical or diagnostic systems and various detection systems may be constructed based on the described systems.
Abstract:
Techniques, apparatus and systems for information collecting and decision making based on networks of sensors and communication nodes for security monitoring and warning, disaster warning, counter-terrorism, and other applications associated with information collecting and decision making.
Abstract:
Techniques, apparatus and systems that use one or more composite left and right handed (CRLH) metamaterial structures in processing and handling electromagnetic wave signals. Antenna, antenna arrays and other RF devices can be formed based on CRLH metamaterial structures. The described CRLH metamaterial structures can be used in wireless communication RF front-end and antenna sub-systems.
Abstract:
Techniques and device designs associated with devices having magnetic or magnetoresistive tunnel junctions (MTJs) configured to operate based on spin torque transfer switching. On-plug MTJ designs and fabrication techniques are described.
Abstract:
Multi-loop opto-electronic oscillators using tunable RF or microwave filters that achieve signal filtering in RF or microwave frequencies by optical filtering and signal tuning by optical tuning.
Abstract:
This application describes whispering gallery modes resonators made of electro-optic materials that are optically coupled to one or two waveguide couplers.
